ANALYSIS (Continued)



DEVELOPMENT

The 'Analyze File' button opens a dialog box that gives access to files on a 

byte-by-byte basis.  The read-group specifies which portion of the file will 

be loaded into memory for analysis.  The determine-bit-depth group, attempts 

to automatically determine the bit depth of the information stored in the 

file.  The dump-group selects the format in which the bytes are presented 

on the screen, either in hexadecimal, or in ASCII-text format.  Either 1024 

hexadecimal or 3072 ASCII characters are presented in the dump window.  The 

search group finds either hexidecimal or ASCII-text sequences in the file. 

The headers group analyzes the header information of file whose formats have 

headers.  Presently only DICOM 3.0 file-format headers are analyzed.





The 'Stopwatch' button is used only during program development. It opens

a dialog box that displays a stopwatch with ten timers. The timers are

set to measure the time taken by sections of code to execute.  The

sections are determined by function calls inserted into the code. Both

single execution and cumulative execution times for a number of repetitions

can be examined.  In addition, the location in the code of the various

timers is shown in a 'Watch Assignments' box.  The text in this box is

taken from the file 'WatchAssignments.txt' located in the ImprocNT

project directory of the MSVC-projects directory.
